STOVE.

Application filed December 20, 1907.

Specification of Letters Patent.

Patented Jan. 5, 1909.

Serial No. 407,301.

To all whom it may concern:

Be it known that I, GEORGE M. ADAMS, a citizen of the United States, residing at Lebanon, in the county of Boone and State of Indiana, have invented a new and useful Stove, of which the following is a specification.

This invention relates to stoves, and its object is to provide a stove of this character having a novel arrangement of flues whereby products of combustion can be directed from the fire box downward under the stove and thence upward to the outlet pipe, said fiues being located entirely outside of and spaced from the stove casing to permit air to freely circulate between the fiues and between the stove and fiues, whereby the effectiveness of the stove as a heating agent is greatly increased.

Another object is to provide means for deflecting or guiding the air currents established between the fiues and the stove casing so that said currents will be directed along diagonal lines and the capacity of the heater increased.

A further object is to provide means whereby the products of combustion can be directed into the heating fiues or, if preferred, can be discharged straight into the outlet pipe, so that the fiues will not operate to heat the surrounding air.

-With these and other objects in view, the invention comprises the various novel features of construction and combination and arrangement of parts, which Will be hereinafter more fully described, and pointed out particularly in the appended claim.

In the drawings :Figure 1 is a view partly in elevation and partly in section of a heating stove embodying the present improvements. Fig. 2 is a section on line a,a of Fig. 1. Fig. 3 is a section on line Z)Z of Fig. 1. Fig. 4 is a section on line 0-0 of Fig. 1.

Referring to the figures by characters of reference, 1 designates a heating stove of any desired construction, and disposed below the bottom of the stove is a substantially U- shaped flue 2 the upper and lower faces of which are preferably parallel with the bottom of the stove, said flue being spaced from and connected to the stove bottom in any preferred manner, as by means of brackets 8. The end portions of the flue 2 project beyond the wall of the stove, and extending upward from these projecting ends are parallel fiues 4 and 5 each of which has its upper end closed. An outlet port 6 extends from the fire box into the upper portion of the flue 4 and another port 7 extends from said fire box into the upper portion of the flue 5, there being a damper 8 of any desired form located within the port 7, so that communication with the flue 5 directly from the fire box can be readily controlled. An outlet pipe 9 for products of combustion extends from the upper portion of flue 5.

It will be noted, by referring to the drawings, that the fiues 4 and 5 are spaced apart and are also spaced from the casing of the stove 1. Interposed between these fiues and the stove casing are deflecting blades 10 arranged preferably in pairs, one pair being located between the stove and each flue, and the deflectors of each pair being inclined downwardly toward the deflectors of the other pair. Moreover, as shown in Fig. 2, the lower deflectors are preferably located at a greater distance from the adjoining or inner walls of the fiues 4 and 5 than are the next adjoining deflectors.

It is thought that the operation of this stove will be readily understood from the foregoing description, when read in connection with the accompanying drawings. When the damper 8 is open, the products of combustion will pass from the stove and through port 7 into the upper portion of flue 5, from which they will escape through the pi e 9. The heating capacity of the stove wil not be increased under these conditions. When, however, the damper 8 is closed, the products of combustion can only pass outward through port 6, and will travel downward through flue 4 to the base flue 2, and after circulating beneath the stove casing, they will travel upward through the flue 5 to the smoke pipe 9. Obviously, the temperature of the walls of the fiues will be raised to a high degree and, as the heating surface of the stove is thus increased in area, the proportion of the surrounding atmosphere which is heated is correspondingly increased. The air is free to circulate between the stove casing and the base flue and also between the vertical flues and the stove. The deflectors 10, however, prevent the heated air from passing upward between these vertical fiues and the stove and act to direct the air currents laterally, thus increasing the capacity of the heater. By spacing the lower deflectors further apart than the next adjoining ones, all of the heated air supplied between the lower portions of the vertical flues and the stove will not be deflected laterally, but a portion thereof will pass upward to the neXt tier of deflectors, this operation being continued throughout the height of the heater.

I claim A heating stove comprising a casing, a base flue there-below, spacing devices interposed between the base flue and the bottom of the casing, there being an open air space between the flue and casing, the ends of the flue being located close together, a down flue outside of the casing and opening at its upper end into the casing and at its lower end into one end of the base flue, an up flue outside of the casing and extending from the other end of the base flue and parallel with but spaced from the down flue, a flue for establishing direct communication between the interior of the casing and the upper end of the up flue, a damper for closing said connecting flue, the up flue being enlarged at its upper end and having a smoke outlet, and inclined baffle plates interposed between the down flue and the casing and between the up flue and the casing, the two sets of plates diverging upwardly and forming inclined air passages there-between, those walls of the base flue and of the up and down lines which adjoin the casing constituting heating surfaces.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.

GEORGE MYRON ADAMS.
